In 30 seconds
This systematic review evaluated the impact of sleep health on weight loss in adults with excess weight undergoing behavioral or surgical interventions. It included 30 studies with 10,944 participants. The review found that sleep restriction may reduce fat loss, while greater sleep satisfaction and higher sleep efficiency could support weight loss, although evidence was mixed.
Key findings
- Sleep restriction was associated with reduced fat loss in behavioral weight loss interventions.
- Approximately half of the studies indicated positive associations between sleep satisfaction and weight loss.
- Evidence for sleep regularity, timing, and alertness was sparse and inconsistent.
Why it matters
Understanding the relationship between sleep health and weight loss outcomes is crucial for developing effective weight management strategies. Clinicians can consider sleep quality as a potential factor influencing the success of weight loss interventions.
